Very recent?  That was from September 8th, over a month ago.  ;-)

It does that for me.

It works for me anyway (With a build updated at most a day ago).  I've
looked at the git log for diff-mode.el, and nobody's changed anything
relevant, that I can see, since early September.

What's your environment?  Operating system, and so on?

Or, maybe something really wierd is happening, and it would stop
happening on an up to date snapshot of Emacs.
